Butterfly Labs (BFL) has lifted the curtain slightly to allow it's customers and the general public a glimpse of their ASIC miner. Currently BFL is the second vendor that is anticipated to bring a fully functioning custom chip miner based on ASIC technology to market. Unfortunately, these miners were promised to be delivered in Oct, 2012 and have experienced significant delays in production since then. As you can see from the video below, it appears the chipset and boards are working but, there appears to be a significant issue with power regulation.
